ABSTRACT:
The present invention provides a newly isolated mutant culture ofActinoplanes teichomyceticusBNG 2315. This culture is capable of producing teicoplanin more than 60 times productivity than those reported before (e.g.,Actinoplanes teichomyceticusnov. sp. ATCC 31121). The present invention also provides a fermentation process for the production of teicoplanin in an aerobic condition using the mutant strainActinoplanes teichomyceticusBNG 2315 in a culture-medium comprising carbon sources, nitrogen sources and mineral salts.
